I don't think Carl got fat and happy. He was trying to win a Super Bowl with Vermeil as fast as possible before Lamar died.
After 2005 everything went south. Was he fat and happy? No, he just made two horrible choices in Herm and Croyle.
The Chiefs will finish 5-11, Alex Smith will play horribly, and Geno and I will cackle with glee while he burns Kansas City.
